Title:Simple and Adaptive Tests for Big Data

标题:简单, 自适应的大数据测试


In this talk, we consider hypothesis testing problems for  big  data where the data dimension may be much larger than the sample size so that traditional multivariate tests are no longer applicable. Via imposing  strong assumptions  on the  underlying covariance matrices, most of the existing tests are shown to be asymptotically  normal  and are conducted using  normal approximation. However, in real data analysis, these imposed assumptions may not be satisfied or hardly checked so that  these existing  tests are less useful.  Unlike the existing tests, we proposed simple and adaptive tests.   Without imposing strong assumptions on the underlying covariance matrices,  the  distributions of  the proposed tests are shown to be asymptotically chi-squared mixtures and are conducted using chi-square approximation. Good performance of the proposed tests is demonstrated via some simulation studies and real data examples.
